I talked to my brother in law last evening about the issue. He is a licenced 
mechanic and has been for maybe 15
years. He says that ABS problems are fairly common, especially on GM products. 
He says that a bit of rust or a
wheel bearing that is a bit loose can trick the ABS into thinking that the 
vehicle is sliding and result in the
computer kicking in the pump which leaves you with a rock hard pedeal and no 
brakes. All it requires is for the air
gap on the sensor to be too big. He says Chevy pickups commonly have the 
problem. You can be pulling into your
garage, hit the brakes, and darned near run into the back wall because it 
suddenly feels like no brakes. He has
less experience with Toyota and therefore cannot say that the design is similar 
and that they might have similar
issues. He suggests looking into the issues carefully if we get the car back to 
try and avoid a repeat performance.

I did wonder about that as well but she did not mention any chattering or other 
indication of ABS malfunction. I
suppose it could be related. I wonder how one tests for something like that?

Randy,
Mis-behaving ABS? My family has had some adventures with ABS
weirdness., like sliding out into an intersection at low speed with
rock-hard brakes = ripple-y road surface confused ABS.
